STM32F407VGT6 Ethernet Module: Jambo frame feature?

Hi developers,

 

I'm new to STM32 MCU, but recently need to use it for a automotive Ethernet board design.

The ethernet PHY I am going to use supports the jumbo frame up to 16kByte. Do anyone happen to know if STM32F407VGT6 can also support this jumbo frame feature or only for standard 1518Byte eth frame?

 

(if not, ss there any MCU from ST suggestion that support this jumbo frame feature. 

 

Thanks!!!

Hello,

Unfortunately STM32F407 MCU does not support Jumbo frames (16kB).

STM32H743 MCU does support Jambo frames. From RM0433 rev 8 page 2779:
